Re: Powering my Pi Zero project

Have a look at the Pi - Juice Hat https://uk.pi-supply.com/products/pijuice-standard It may be a squeeze and cabling challenge depending on how other things are connected... In my project, there's not enough space to store the battery in HAT mode, so I have to use a product that has it's own pins a...

Re: Powering my Pi Zero project

How much current do you need to supply? I use Powerboost 1000c's on a few of my Pi builds but they have a 1 amp output limit. https://www.adafruit.com/product/2465 And there is this which is good for up to 2.5A https://www.dfrobot.com/index.php?route=product/search&search=MP2636 I am not entirely s...

Powering my Pi Zero project

I am close to finished with my project that features Pi Zero, 10 RGB LEDs, Arduino micro and DAC for a small 3W speaker. But I have trouble with the current power source — USB power bank. One thing is that it briefly cuts the output power when disconnected from the wall socket, but I managed to solv...

Re: Pi Zero W accessible via SSH only after long time

Thank you all for suggestions. The messages from the startup what I mentioned in my post were hand-written from the display connected to HDMI. So I have no problem seeing what's going on, at least if that is reflected in the HDMI output. What I failed to mention is that I have Arduino Micro connecte...

Pi Zero W accessible via SSH only after long time

I have set up my router to assign IP(v4) fixed address to the Pi Zero W. IPv6 is disabled on router. I have loaded Raspbian Stretch Lite on the SD card. When I power it up, among the last on-screen messages, among those are: [ OK ] Reached target Network ...(some more lines) My IP address is 192.168...

Re: I2S DAC, alsamixer: device does not have any controls

Hello, My project is a media player, hidden in a kids toy (pimped-up vintage dial phone). I have set up my Pi Zero with MAX98357A amp, and used the asound.conf example from this thread to get the software volume control. I have installed vlc-nox package that includes vlc headless player, to play mp3...

How to look for an appropriate screen?

I am planning to replace the lousy PC that sits in my car's navigation computer bay ( looking like this ) with RasPi 2. But I plan to keep the existing casing, because it contains cool mechanics that raise and lower the display from the car's front panel. So I have pulled out the casing, stripped it...

Re: USB wireless keyboard not active after boot

It's Logitech K400: http://www.logitech.com/en-us/product/w ... board-k400
It doesn't seem to drop keys but only this startup recognition problem. The result of lsusb command is exactly the same when the dongle is pulled out and plugged back again.

USB wireless keyboard not active after boot

I have wireless keyboard/trackpad USB dongle attached to my Pi, and after reboot it doesn't seem to receive signals from the keyboard (rarely, but sometimes it works tho). If I ssh to the Pi and do lsusb, then I see the respective Logitech device in the list. If I'd now remove the USB dongle and plu...

Boot to Wheezy by default, keep XBMC as application

Hello, I followed instructions from http://elinux.org/RPi_XBMC to install the XBMC on Wheezy, because I wanted to keep using my Pi (Model B, with 512Mb RAM) for other projects in Wheezy. So, OpenELEC is not an option in my case. But I experience several problems in this setup, I hope they are easy t...

CEC reading

Hello,

I am looking for a way how to listen to CEC signals (the one over HDMI) in Python app?

Perhaps the "right way" is to install libCEC and wrap it for Python access, but I have too little knowledge to do it on my own.

Access the default running X desktop session over VNC

Hello, I'd like to access the default running (vs virtual) X desktop session (the one that is visible over HDMI) over VNC - basically to use my laptop as kbd+mouse while enjoying the big TV screen connected to my Pi. I don't want to invest in extra kbd+mouse for Pi, when several network-connected la...
